Constructor Summary

GenericArrayEditor()
Sets up the array editor.

Method Summary

void	addPropertyChangeListener(java.beans.PropertyChangeListener l) Adds a PropertyChangeListener who will be notified of value changes.
java.lang.String	getAsText() Returns null as we don't support getting/setting values as text.
java.awt.Component	getCustomEditor() Returns the array editing component.
java.lang.String	getJavaInitializationString() Supposedly returns an initialization string to create a classifier identical to the current one, including it's state, but this doesn't appear possible given that the initialization string isn't supposed to contain multiple statements.
java.lang.String[]	getTags() Returns null as we don't support getting values as tags.
java.lang.Object	getValue() Gets the current object array.
boolean	isPaintable() Returns true to indicate that we can paint a representation of the string array

void	removePropertyChangeListener(java.beans.PropertyChangeListener l) Removes a PropertyChangeListener.
void	setAsText(java.lang.String text) Returns null as we don't support getting/setting values as text.
void	setValue(java.lang.Object o) Sets the current object array.
boolean	supportsCustomEditor() Returns true because we do support a custom editor.
private void	updateEditorType(java.lang.Object o) Updates the type of object being edited, so attempts to find an appropriate propertyeditor.
